Abstract :
A novel magnetotransistor using a separated drift field has been designed and fabricated. The measured relative sensitivity of the magnetotransistor agrees well with the analytical value based on the emitter injection modulation model. The separated drift field, which is independent of the carrier injection, can maximize the effect of emitter injection modulation. In the saturation mode, the relative sensitivity is greatly increased by the drift of electrons due to the lateral field in the emitter
